Welcome to the Peregrine Falcon (Falco peregrinus) Home Page 2014

Another year at the University of Calgary, another potentially promising season with the arrival of the first peregrine falcon on March 31st, 2014. It was spotted (no i.d. made yet) on its 'usual' vantage spot, the west-facing top roof area of Social Sciences.

Judy Powell and Irene Wade were able to both confirm the arrival of the first falcon March 31st. 

Two adults have been seen participating in usual courting activities, with the male (now confirmed to be 'Gary' - prev. mate of 'Callie') bringing food to the female, and our female spending time in the scrape and fussing about.
